Robertson AP11 Autopilot
8 20220513E
The AP11 autopilot system includes NMEA0183 input and
output ports. The NMEA input allows a single navigation
receiver and speed and wind sensors to provide input to the
system. The NMEA output provides heading and rudder
angle to separate IS11 instruments or to the IS11 Databox.
Depending on the autopilot configuration and the
equipment that may be connected to the NMEA input,
other NMEA data may also be available at the NMEA
output.
The time proven experience of the Robertson engineers and
the computer power in the AP11 system has made it
possible to automate and simplify the setup and installation
procedures. One important feature is the capability to set up
automatically the steering parameters and select the scaling
factor for speed and hull type; power (planing or
displacement) or sail. Proportional rate output commands
and an adaptive sea state filter contribute to enhanced
steering performance in any sea condition.
